Narrative:

I was holding at the hgr VOR at 4500 MSL as published on the hgr VOR runway 9 approach. I arranged with ZDC on 134.15 to do 2 practice instrument approachs under VFR at hgr. I had been assigned a discreet squawk and had radar contact established about 10 min earlier! I was inbound on the holding radial when I was advised of a 'bae 31' inbound from the west leaving 5000 landing hgr, traffic reported to be at my 11 O'clock position. I reported to ZDC that I was looking but did not see traffic. My vision was partially blocked by my student's hood, used for instrument training. Even though I leaned forward to look around his hood, I still could not see the traffic. About 20 seconds later, I again leaned forward to scan for traffic on the other side of my student when I saw the (air carrier). Bae 31 descending to our altitude on a collision course from our left side! I took control of the airplane from my student and made a hard right turn to avoid a collision course from our left side! I took control of the airplane from my student and made a hard right turn to avoid a collision with the other aircraft. I advised the controller of the situation. He then contacted the (air carrier) and asked if he saw us pass off his right side. They said they never saw us. I find the IFR training hood to be very limiting on visibility out the left side of the aircraft. I felt the controller should have taken action to turn, climb or descend 1 of the aircraft! No pilot had the other aircraft in sight!

Title: NMAC BTWN AN LTT DSNDING OVER A VOR FOR A VISUAL APCH AND A SMA SEL TRAINING FLT HOLDING VFR OVER THE SAME VOR.

Narrative: I WAS HOLDING AT THE HGR VOR AT 4500 MSL AS PUBLISHED ON THE HGR VOR RWY 9 APCH. I ARRANGED WITH ZDC ON 134.15 TO DO 2 PRACTICE INST APCHS UNDER VFR AT HGR. I HAD BEEN ASSIGNED A DISCREET SQUAWK AND HAD RADAR CONTACT ESTABLISHED ABOUT 10 MIN EARLIER! I WAS INBOUND ON THE HOLDING RADIAL WHEN I WAS ADVISED OF A 'BAE 31' INBOUND FROM THE W LEAVING 5000 LNDG HGR, TFC RPTED TO BE AT MY 11 O'CLOCK POS. I RPTED TO ZDC THAT I WAS LOOKING BUT DID NOT SEE TFC. MY VISION WAS PARTIALLY BLOCKED BY MY STUDENT'S HOOD, USED FOR INST TRAINING. EVEN THOUGH I LEANED FORWARD TO LOOK AROUND HIS HOOD, I STILL COULD NOT SEE THE TFC. ABOUT 20 SECONDS LATER, I AGAIN LEANED FORWARD TO SCAN FOR TFC ON THE OTHER SIDE OF MY STUDENT WHEN I SAW THE (ACR). BAE 31 DSNDING TO OUR ALT ON A COLLISION COURSE FROM OUR L SIDE! I TOOK CTL OF THE AIRPLANE FROM MY STUDENT AND MADE A HARD R TURN TO AVOID A COLLISION COURSE FROM OUR L SIDE! I TOOK CTL OF THE AIRPLANE FROM MY STUDENT AND MADE A HARD R TURN TO AVOID A COLLISION WITH THE OTHER ACFT. I ADVISED THE CTLR OF THE SIT. HE THEN CONTACTED THE (ACR) AND ASKED IF HE SAW US PASS OFF HIS R SIDE. THEY SAID THEY NEVER SAW US. I FIND THE IFR TRAINING HOOD TO BE VERY LIMITING ON VISIBILITY OUT THE L SIDE OF THE ACFT. I FELT THE CTLR SHOULD HAVE TAKEN ACTION TO TURN, CLB OR DSND 1 OF THE ACFT! NO PLT HAD THE OTHER ACFT IN SIGHT!
